l»roviiice, whore (k'lxrsits of tliis kind occur siiiiiliir to 

 thosu found in ("iinuda and in Maino, Lhou,i,di apparently 

 on a smaller scale. These dei)osits, as they oceur near 

 8t. .lohn, consist of ^'ray and reddisli elays, holdin.i,' fossils 

 which indicate moderately deep water, and are, as to 

 si)ecies, identical with those oecurrini,' in similar dejiosits 

 ill (.'anada and in Maine. They would indicate a some- 

 what lower temperature than that of the waters of the 

 hay of Fundy at i)resent, or ahout that of the northern 

 part of the gulf of St. Lawrence. 



In JJailey's lleport on the (leohi^ify of Southern New 

 Brunswick, Professor Hartt has (•iven a list of the fossils 

 of these heds, as seen at Lawlor's lake, Duck cove and 

 St. -John, which 1 re-published with some additions in 

 Acadian (Jeology. 



The.se New 15runswick heds are strictly continuous 

 with, and eipiivalent to those which extend alon^i,' the 

 coast of New En<,dand, and thence ascend into the valley 

 of lake Champlain, while on the other side they may he 

 considered as perfectly re])resentin,ti[ in character and 

 fossils the Leda clay of Eastern Canada. They are 

 remarkably like l)uth in mineral character and fossils to 

 the Clyde beds of Scotland, which are probably their 

 equivalents. The points of resemblance of the Leda clay 

 of the coast of Maine, and that of the St. Lawrence, and 

 Labrador, were noticed by me in my paper of 18G0, 

 already referred to, and have been more fully brought 

 out by Dr. Packard, who describes the Leda clay as it 

 occurs at several localities from Eastport to cape Cod. 

 Along this whole coast it retains its Labradoric or gulf of 

 St. Lawrence aspect, though with the introduction of 

 some more southern species, and the gradual failure of 

 some more arctic forms. South of cape Cod, as in the
